ICR suspension adjustments

by Andrew R. Tef » Tue, 27 Jun 1995 04:00:00

I think I am at a point now where I really need to start tweaking
my shock stiffness and anti-roll bars -- at least one some of the courses
I can drive consistently enough to make a difference.

What's the best way to tell how my suspension needs adjusted? Will
tire temps be an indication (just talking about shock stiffness here,
not camber)? or do you have to go purely by handling 'feel'? The manual
is a bit sparse here and it seems contradictory in a couple of places
to me, but maybe just because I don't understand the concepts fully
enough. The main advice is about adjusting front vs. rear to deal
with understeer and oversteer, but I am mainly interested in the left/right
balance.

  I'm having trouble with shock adjustments too.  The harder you put
one shock relative to the other, the more responsive but less grip
that tire has.  The software you make that shock, the more grip and
less responsive that tire.  I think it also keeps the temperature lower
since it doesn't slide as much.  I find that softening front right gives
a bit more grip in ovals... on road courses I'm usually totally confused
as changes never react the same way on any track.  All I know is
suspension is really important to the car setup, I'm thankful that papyrus
gave pretty good suspension settings in the default setups.  If you know
how to do suspension setups well, you can go much faster... the more
mechanical grip you get the less aerodynamic grip you need.  Which means
flying down the straightaways AND going pretty fast around the corners.
Hopefully someone else who knows how to build REALLY good setups will
post about this.  I just know the very basic concepts. :(

Find the "paper" NCWW something or other.  It details in
excellent detail how to set up a NASCAR stocker.  However, the
principles are the same for an Indycar on ovals.  For road
courses, there are a LOT of compromises but the general idea is
the same.
